What is a steel i beam building.
													
																	Steel beam roof construction. 
									
	
		
	
																	Steel support beams for residential construction costs 100 to 400 per foot to install or between 1 200 and 4 200 extra costs apply for knocking down walls rerouting utilities or adding underpinnings for support. 
																	Steel i beams can be used on residential construction. 
																	Steel is cheaper than wood in most cases and it can handle a load much better but steel beams must usually be cut off site and trucked into a location whereas wood beams can readily be cut on site. 
																	However a steel beam design might require special handling. 
															
													
									
	
		
	
																	Structures that use steel roof beam construction usually have flat roofs but some smaller structures may have a peaked roof. 
																	There are two sidewall columns and two roof beam sections. 
																	In a steel i beam building the main frame is constructed from steel and acts as the support for the building. 
																	Each i beam truss is raised and bolted or formed into the concrete foundation. 
															
													
									
	
		
	
																	A truss is a member with four sections assembled on the ground. 
																	Steel beams can be designed to act compositely with a concrete slab by the use of shear connectors normally in the form of welded steel studs that are welded at regular spacing to the top flange of the steel beam. 
																	A composite edge beam with galvanised steel decking orientated parallel to the beam is shown. 
																	Before the new steel beam was lifted to the roof leaders and the construction crew held a signing ceremony penning their names and the date in sharpie on the new beam. 
															
													
									
	
		
	
																	A steel i beam costs 6 to 18 per foot for just the materials.
